ooc: Artillery piece.
Description:
The ATR-12 Gemnia is a truck based artillery piece capable of rapid movement. Based off a MP Motor Works Corporation 8x8 Gnu truck, the ATR-12 weighs only 19 tons and is fully capable of being paradropped or lifted by heavy helicopter/cargo aircraft. The ATR-12 is designed for rapid reaction force deployment, but makes for a solid standard self-propelled artillery piece.
Armament:
The ATR-12 Gemnia is equipped with a 155mm, 56 calibre barrel and can maintain 8-10 rounds per minute sustained fire and up to 3 rounds in 10 seconds with its burst fire option. The chamber and barrel are surrounded by Thymonel-8 piping filled with Aerogel, which helps to absorb and distribute the heat generated by them more evenly. Also, the chamber and barrel are reinforced with Inconel-8 and NiAl superalloys so that they can both stand up to far greater than normal barrel pressures. The weapon has a recoil length, variable from 600 to 1500mm.
The MPCN-1 standard force networking communication system is fitted, as is a trajectory calculation computer with ballistic tables, wind and barometric sensors, and projectile velocity calculation radar. GPS, compass and inertial navigation suites are fitted, and linked with the MPCN-1 systems so that infantry can easily Lastly, the Shtora-V ECS/Remote Control system is fitted, so that infantry in the field can remotely fire the weapon if the crew is disabled or not present.
The weapon has a set of 4 automatic hydraulic anchor spades and the loading system is semi-automatic, meaning that spent cartridges are quickly ejected. A powered shell lifting crane is mounted in the back in order to assist the loader in loading shells more quickly. The gun has a small rotating rack in the rear, with a set of hydraulic rams. The rack allows the gun to be loaded with up to 6 ready fire rounds at once.
The ATR-12 is fitted with the FC3S-4 standard Fire Control System. The system provides onboard terminals for communications and real-time firing sequence management including forwarding of fire-support requests and transmission of firing orders according to target type, ammunition type and gun availability. The FC3S-4 can also keep track of thousands of potential targets at once, and maintains target data on all of them, so that it can be ready to fire on any of the tracked targets at once.
The gun can be set into and out of action in less than 45 seconds, using variable drive hydrodynamic actuators and a rotating turret drive built into the bed of the truck. The actuator mechanisms are also responsible for raising, lowering and traversing the gun.
Munitions:
The following munitions can be shot from the ATR-12 Gemnia:
*Base Bleed Munitions: Base bleed munitions are munitions that store some of the gas from the detonation of the propellant, in order to reduce drag vacuum that is created in the rear of the shell, thus increasing the range. The base bleed munitions fired from the ATR-12 can travel up to 50km.
*VLAP Shells: Both single and dual stage propellant VLAP shells can be fired from the ATR-12. The VLAP shells tend to sacrifice some explosive capability for longer range, but they can travel a whopping 75km kilometers with the dual stage propellant shell. The VLAP shell is especially useful for applications that require a great deal of reach, but not a large amount of explosive.
*Rocket Assisted Projectiles: Rocket assisted projectiles from the ATR-12 can travel up to 90km. Rocket assisted shells are fairly useless for general artillery purposes, because they carry little explosive. However, a creative player can find other uses for RAP shells.
*Subcaliber Rounds: A subcaliber projectile can be fired from the 155mm gun. The distance it travels is dependent on the size of the subcaliber projectile.
Long Chamber Round: The ATR-12’s chamber is significantly longer than a standard 155mm gun’s chamber. Thus, longer rounds loaded with more propellant can be fired from the ATR-12. The LC rounds can also be equipped with base bleed, RAP and VLAP upgrades.
Munition Payloads: The ATR-12’s shells can carry many different payloads. Some of the more commonly used payloads are as follows, although the user is free to fire a custom formulated payload.
High Explosive Fragmentation: This fairly common artillery round is used for destroying all manner of things and is especially deadly to advancing infantry and other soft targets.
High Explosive Directed Fragmentation: The directed fragmentation blast shell stuffs the extra space in a hollow charge round with heavy shrapnel. When the hollow charge detonates via a proximity fuse, it blasts the stream of shrapnel into a narrow arc in front of it. This round is especially useful for clearing out trenches, as a decent blast can be aimed into a trench, instead of a blast being focused around it, allowing for the pieces of ping-pong sized silicon carbide shrapnel to bounce around down the length of the trench, shredding anything inside.
Incendiary: Incendiary shells spray a mixture of white phosphorous, napalm and granulated thermite in every direction. This sort of shell is very, very effective against dug in infantry, because they have no place to run to once the shell bursts over them.
Thermobaric FAE: Thermobaric FAE rounds can literally flatten soft structures, crush soft vehicles like tin cans and vaporize infantry, all through sheer overpressure.
Anti-Tank: Anti-Tank rounds are filled with baseball sized pieces of depleted uranium or nanocrystalline tungsten. The submunitions are designed to go through the roofs or engine compartments of armored vehicles, shredding them to pieces to get at the inside. The rounds are machined to discharge their submunitions in 2 closely timed waves in order to defeat top reactive armor.
EMP Rounds: Airburst EMP rounds can be used to destroy enemy electronic devices. Generally, the blast radius is spherical in nature; however, the shell can be programmed to blast out a circle if necessary.
Cluster Grenades: A variation on the High Explosive Fragmentation round. Each individual cluster grenade is loaded with high blast explosives and they are designed to travel through the roofs of buildings, open windows, or walls before blowing up. They are very useful for clearing out buildings. Non lethal versions of this round can be filled with flashbang or tear gas grenades.
Obviously there are many other types of shells, but these are just some of the few that are available for the ATR-12.
Propulsion:
The ATR-12 Gemnia is mounted on an MP Motor Works Gnu 8x8 flatbed truck. The Gnu has a standard 2-stick transmission coupled to a 900 horsepower diesel/electric quasiturbine. It can travel up to 900 km unrefueled and go up to 110 km/h on road. The truck has multiple Torsen differentials and traction sensors, so that it can traverse rough terrain.
Excluding ready ammunition supply, the ATR-12 can be carried in a single load of a C-130 Hercules transporter.
